Core Concepts
Synthesizing robust output feedback controllers for path planning in robotics.
Abstract
The content discusses the design of output feedback controllers for path planning in robotics, focusing on stability and safety using Control Lyapunov and Barrier Functions. It explores the integration of high-level path planning with low-level control processes to navigate through environments efficiently. The approach is tested in simulation environments under practical conditions like limited field of view measurements.
I. Introduction:
Path planning in mobile robotics focuses on finding trajectories while ensuring collision avoidance.
Biological systems demonstrate flexible navigation capabilities without detailed maps.
II. Notation and Preliminaries:
Defines system dynamics, constraints, and relative degree concepts.
III. Problem Setup:
Synthesizes robust controllers for convex cells using linear programming.
IV. Control With Limited Field of View:
Discusses rescaling bearing measurements for controller design.
V. Control With Bearing Measurements:
Explores rescaling bearings to simulate full displacements for controller synthesis.
Stats
We propose two objectives for navigating in an environment: traversing by making loops or converging to a stabilization point smoothly between cells.
The work integrates high-level path planning with low-level control processes to design robust output feedback controllers.
The approach is tested under practical conditions like bearing-only measurements and limited field of view.
